摘要
针对空调管路内部因存在微小焊堵会出现换热器分液不均、影响制冷系统的正常运行的问题,对比行业现有空调管路的焊堵检测方法,开展管路焊堵流道仿真模型及其检测方法的研究。利用流体仿真软件对比分析了各种流道压损干扰因子及其排除方法,结合实物对比模拟测试结果,采用单一支路口进气,堵住其他支路口的测试方案,通过使用高精度流量设备,以2%的流量偏差,可识别管路微小焊堵状态。
Aiming at the problem of uneven welding of the heat exchanger due to the existence of small welding plugs in the air conditioning pipeline,which affects the normal operation of the refrigeration system,the welding plug flow path simulation of the pipeline is compared with the existing welding detection methods of air conditioning pipelines in the industry Research on models and their detection methods.Using fluid simulation software to compare and analyze various flow channel pressure loss interference factors and their elimination methods,combined with physical comparison simulation test results,using a single junction intake,blocking other branch junction test scheme,by using high-precision flow equipment,with a flow deviation of 2%,it can identify the state of the small welding plug of the pipeline.
